A point P (a, b) is reflected in the x-axis to P' (2, 3). Write down the values of a and b. P" is the image of P, reflected in the y-axis. Write down the co-ordinates of P". Find the co-ordinates of P", when P is reflected in the line, parallel to y-axis, such that x = 4.

Solution

The coordinates of the point P be(2,-3)

Hence the value of a and b are
2and -3 resp.

after reflection co ordinates of P"=(-2,3)

Coordinates of p after reflection from x=4 are (6,-3)
